Build problem-solving skills with science! Step-by-step videos walk investigators through each stage of completing a science fair project. Scientists learn to formulate a testable question, design an experiment, collect data, draw...

Do you find the idea of having a science fair with all of your students intimidating? Use a guide that provides everything you need to know to make project-based learning manageable. The resource includes options for four...

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Waxed paper, newspaper, or aluminum foil? Keeping an ice cube from melting may require one or more of these materials. Learners design a box that will provide insulation so an ice cube stays intact for at least 90 minutes.

Discover the power of wind energy. Learners design, build, and test wind blades in a hands-on experiment. They analyze the results to determine if they can make any improvements before gathering as a class to discuss their designs.

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Capillary action is the frugal chemist's dream ... the less liquid used, the more tests they can run! Learners experiment with the best design to maximize the benefits of capillary action. Using a liquid sample, they design a capillary...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Should athletes carb load before an event or consume carbohydrates during the competition? Scholars discuss how to set up a hypothesis and experiment to answer a question relating carbohydrates and athletic performance. Then, they read...

Step aside, fancy glasses... it's time to create a solar eclipse viewing camera of your own using nothing more than a milk carton. 

A phantom of neuroscience may leave pupils perplexed as they engage in an experimental lesson that recreates a phantom limb scenario. After experiencing the phenomenon, they choose a scientific question to explore further.

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Space, the Final Frontier. The nine NASA-created challenges in this unit are designed to teach class members the engineering design process. Each challenge comes with teacher and student pages that can be used individually or as a...

It may be gruesome but somebody's got to do it! Young forensic scientists get a feel for what the job entails as they study blood spatter in seven experimental activites. They examine how spatter can be changed by release height,...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

What if you had a design problem you wanted to solve, but were unable to draw because you were unable to see? Teach your learners with visual impairments that they can use Wikki Stix®, a braille ruler, Legos®, and Constructo Straws to...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

Investigate a heated topic in environmental science. Scholars team up to play the parts of gas molecules in the atmosphere. As the teacher moves about, acting as the electromagnetic wave, learners react as their molecules would to the...

Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...

Oh, no! An asteroid is on a collision course with Earth!. Class members must rise to the challenge of designing a shelter that will protect people from the impact and permit them to live in this shelter for one year. In this first lesson...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.
